Ich habe ein wirklich seltsames Problem. Ich habe meine MainActivity mit einer TabFragment mit 4 Tabs. 3 dieser Registerkarten haben den gleichen Stil mit einer Liste von Threads. Die drei Registerkarten sind Active, Watching und I'm On. Das Problem, das ich habe, ist, dass, wenn ich auf ein Element in Watching klicke, es den Thread von der gleichen Position in Active lädt. Ich habe den onClick in meinem Adapter implementiert, weil es nur ein bestimmter Teil des RecyclerView ist, den ich anklicken möchte, um zu dieser Seite zu gelangen, und ein anderer Teil, um das Kontextmenü zu öffnen.Falscher Artikel wird geladen in RecyclerView in TabFragment
Ich weiß nicht, wie ich dieses Problem lösen soll und ich bin mir nicht einmal sicher, ob der Titel mit dem Thread übereinstimmt, da ich nicht weiß, wonach ich eigentlich suchen möchte.
Hier ist mein Code, um den Adapter in einem der drei Fragmente zur Einstellung
mAdapter = new WatchedThreadAdapter(getContext(), mData);
mRecyclerView.setAdapter(mAdapter);
und hier ist der onClick innerhalb des Adapters
mContext.startActivity(ActivePostPagerActivity.createIntent(mContext, position));
Meine WatchingFragment wie folgt aussieht:
public class WatchingFragment extends Fragment {
private View mRootView;
private RecyclerView mRecyclerView;
private GridLayoutManager mLayoutManager;
private ThreadResponse mData;
private WatchedThreadsRequestData mRequestData;
private RecyclerView.Adapter mAdapter;
private TextView mNoThreadTextView;
private int mDataSize;
private MyReceiver r;
public WatchingFragment() {
// Required empty public constructor
}

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mRootView = inflater.inflate(R.layout.fragment_watching, container, false);
if (savedInstanceState == null) {
initUI();
}
return mRootView;
}
private void initUI() {
mRecyclerView = (RecyclerView) mRootView.findViewById(R.id.watchedThreadRecyclerView);
mNoThreadTextView = (TextView) mRootView.findViewById(R.id.noWatchedThreads);
mLayoutManager = new GridLayoutManager(getActivity(), 1);
mRecyclerView.setLayoutManager(mLayoutManager);
mRequestData = new WatchedThreadsRequestData(getActivity());
registerForContextMenu(mRecyclerView);
/* mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener

}
private void loadData() {
mRequestData.getWatchedData(new WatchedThreadsRequestData.WatchedThreadsFeedback() {
@Override
public void onWatchedRequestReceived(ThreadResponse response) {
mData = response;
populateUIWithData();
mDataSize = mData.getItems().size();
}
@Override
public void onWatchedRequestFailed(Exception exception) {
}
});
}
private void populateUIWithData() {
if (mData.getItems().size() == 0) {
mNoThreadTextView.setVisibility(View.VISIBLE);
mRecyclerView.setVisibility(View.GONE);
} else {
mAdapter = new WatchedThreadAdapter(getContext(), mData);
mRecyclerView.setAdapter(mAdapter);
mAdapter.notifyDataSetChanged();
mRecyclerView.setVisibility(View.VISIBLE);
mNoThreadTextView.setVisibility(View.GONE);
}
if (mData.getItems() != null && mData.getItems().size() > mDataSize) {
mAdapter.notifyDataSetChanged();
mDataSize = mData.getItems().size();
}
}
/* private void showItemSelectedAtPosition(int position) {

Bitte geben Sie Fragment und Adapter-Klasse Code, so dass diese Frage spezifischer –
